The Benefits of Using a Torque Limiter
Using a torque limiter can be very beneficial, as it can save a lot of energy in the long run. It can also be used to protect a piece of equipment from damage, as it will protect the item from being overloaded. This is an important factor in many industries, and can save a lot of money.
Placement of a torque limiter
Typically, a torque limiter is located at the output of an electric motor, a gearbox, or other rotating mechanism. It is used to limit torque to a preset level. The torque limiter protects the motor or gearbox from overload and jamming. Torque limiters are used in industrial robots, conveyors, and sheet metal processing equipment. Using a torque limiter can save you money and protect your machinery from damage.
Torque limiters are available in various sizes and can be used in practically any application. The most important criterion for choosing a torque limiter is drive torque. It is important to place the torque limiter near the drive train to ensure maximum protection. The torque limiter must be larger than the output shaft of the motor.
Ball detent torque limiters are a popular type of limiter. These limiters use balls or rollers in sockets to decouple the drive and driven elements. When the torque exceeds a preset level, the balls slide out of the sockets.
Torque limiters come in various forms, including mechanical, pneumatic, and magnetic. These limiters can be used in any environment and provide advantages in certain niche applications. These limiters are easy to install and replace. They can also be adjusted to provide the desired slipping torque.
Friction torque limiters are a simple, low-cost method of protecting the higher cost components of a machine. They operate similarly to automotive brakes, using hardened balls or rollers in sockets to decouple drive and driven elements.
Ball detent limiters are usually adjustable through a rotating collar. The balls or rollers try to engage the next set of detents when the torque exceeds the preset level. A ball detent limiter can also have a snap acting spring.
Torque limiters can also be packaged as shaft couplings. This allows for the limiter to be placed between a gearbox and the motor, preventing overload and jamming.
Electronic torque limiters are also available. These limiters can be adjusted to the torque required for a particular machine cycle. This feature is especially useful in applications where linear load increases at a slow rate. A torque limiter may also have a trip indicator.
Magnetic torque limiters
Using magnetic torque limiters can improve the performance of your equipment. It can prevent the risk of catastrophic failure, which can lead to extensive repairs. It can also be a cost-effective way to prevent damage.
There are two different types of magnetic torque limiters. One is the synchronous magnetic torque limiter, which uses permanent magnets mounted on each shaft. The other is the aeronautical magnetic torque limiter, which is designed to operate in line with a mechanical gearbox.
Torque limiters are typically used in sheet metal processing, printing and converting equipment, and robotics. They can also be used on conveyors and in other automated applications. These devices are commonly made of heat treated steel.
Magnetic torque limiters can be used in a wide range of temperatures. Compared to friction torque limiters, they don’t wear out as quickly and are less prone to fatigue. They also have quick response times. They don’t require lubrication. They are also easy to maintain. The parts are sealed with thread locking adhesive. They also require less clearance, which prevents wear.
Torque limiters are also known as overload safety devices. These devices prevent unnecessary downtime by disconnecting a motor from a driven system when a torque load reaches a specified limit. They can also prevent workplace accidents. They are typically used in conveyors, woodworking machines, and industrial robots.
Magnetic torque limiters are typically more expensive than friction torque limiters. They are also not as easy to integrate into a system as friction limiters. They are also not suited for applications with high torque demands. The magnetic torque limiter has a greater backlash than the friction type. However, they can be used in a variety of applications, and they don’t require continuous maintenance. They also offer a degree of torsional elasticity.
The aeronautical magnetic torque limiter is designed to withstand up to 200 overload events. Its design has been tested to operate at a temperature range from -50 degC to +90 degC. It has been shown to work correctly throughout the range.
It is important to place torque limiters in the right location. They should be placed between expensive mechanisms. They also should be positioned to prevent tripping.
Friction torque limiters
Often considered an old technology, friction torque limiters have a lot to offer. They are low cost, simple mechanical devices that can prevent damage from overloads. A proper understanding of these devices can help you select the one that is right for your needs.
Friction torque limiters work by removing rotational energy from the drive train. They are typically used in industrial and agricultural machinery, as well as in textile processing and assembly lines. The units are available in several different sizes and formats.
Torque limiters are available as ball detent units, shaft-to-shaft couplings, and even friction units. They operate similarly to automotive brakes. However, they are much more predictable than their cousins. The amount of torque transmitted by the unit can be adjusted with a hand-operated knob. They can also be combined with other drive components to provide additional flexibility.
These units are typically made of black phosphated steel. They feature a flanged or threaded hub and two friction rings. They are available in various sizes and come in simplex, duplex, and triplex versions. The hub can be mounted on a pulley or sheave.
Depending on the application, friction torque limiters may be used in both directions of torque transmission. They can be paired with flexible coupling to accommodate small angular misalignments. Some systems are available in a single position, while others offer a random reset device.
When a torque overload occurs, the torque limiter slips until the overload is overcome. The unit also acts as a clutch, allowing the output side to stop rotating until the overload is resolved.
The design of friction torque limiters allows for a wide range of torques. Depending on the application, the units can operate at high speeds. However, they are not recommended for applications that use high speeds because they can heat up, overheat, and produce unwanted wear.
For applications that require higher torques, it is a good idea to use a torque sensing device. This allows the operator to adjust the settings to prevent overloads. It is also useful in applications where torques are varying due to temperature or humidity.
Over-torque limiters
Various mechanical overload devices are used to prevent damage from accumulated rotational energy. Some are also called slip clutches. They disconnect a drive from a driven component when the load exceeds a pre-determined torque threshold.
Mechanical overload devices are often used in applications that require high torque levels. For example, windmill test stands and industrial crushers require operation at torque levels greater than 10 KNm. They are also used in gas turbines. Some are designed for industrial gearboxes and stepper motors. They are also used in marine applications.
Mechanical overload devices are available in various designs, including pawl-detent, ball-detent, and friction. These devices are adapted for various applications, including high-speed operation, light weight, and high accuracy.
Ball-detent torque limiters work by transmitting force through hardened balls. These limiters have been used for hundreds of years, but are more sophisticated now. They can be configured with multiple detent positions, and may also include a compression adjustment. They may require a manual reset after an overload.
Other mechanical overload devices include friction and hydraulic torque limiters. The friction type works by generating torque between contact surfaces. These devices may also employ friction plates. The hydraulic type applies hydraulic pressure between free spinning surfaces. They may also employ shear ring or shear tube designs.
Mechanical overload devices can disengage a drive line from a driven component within a few milliseconds after an overload occurs. These devices can also adjust the torque limit by using a single screw. These devices may also include proximity sensors to detect the source of a jam.
A torque limiter may also be implicated in no-start conditions. These systems may emit a noise on start up, but should not be accompanied by squealing or rattling. If a torque limiter is malfunctioning, it may be damaged or incorrectly installed. This will lead to unplanned downtime and increased maintenance costs.
Torque limiters may also be used to prevent collisions between production machines. These devices can disengage a drive from a driven component when it encounters a collision. Some designs may also incorporate safety couplings. This will reduce the risk of damage to the drive or the workpieces.
